White: king f1; queen d3; rook d1; bishop f6; pawns a2/c2/e5/f2. Black: king c8; queen g4; rook e8; knight b8; pawns a7/c6/e6/f7/g6/h5. Black is ahead by 2 points of material. White to move.
White executes a three-move sequence that systematically corners Black's queen and forces its capture. After 1.Qb3, the queen controls the long diagonal and cuts off the Black king's escape routes toward the center. Black's 1...Qe4 (attacking f3) is forced to stay active, but 2.f3 traps the queen further — it has no safe square on the e-file (the rook on e8 blocks retreat) and moving to d5, c4, or a4 leaves it on files and diagonals White's rook and queen now dominate. When Black plays 2...Qd5, hoping for centralization, 3.Rxd5 simply captures. The queen is overworked defending itself while Black's king on c8 remains trapped in the corner with its knight on b8 undeveloped — no piece can interpose or defend the queen on d5 because White's rook has the entire d-file to itself.
In endgames with an active but exposed enemy queen, look for pawn moves that restrict its escape squares while your pieces control key files and diagonals. Here, f2-f3 is a quiet move that doesn't attack the queen directly but removes its f3 square and prepares to support the rook's control of the d-file. The pattern: limit the opponent's piece mobility through prophylactic pawn advances, then harvest the trapped piece. This teaches patience — the winning move isn't a flashy sacrifice but a simple pawn push that tightens the noose.
